Re: Weaning 19 mo; 2.5 mos pregnant
Aside from the travel you have planned, is there any reason why you want to wean? It's fine if you do- I just personally think travel isn't a good reason to wean. Quite the opposite, in fact, because nursing can be a great way to ease a child through the stresses of travel or to reconnect with your child when you get home.
I don't think anyone has really quantified how much immunological benefit a child is likely to receive from x number of nursing sessions at x years. But it is known that as breastmilk quantity decreases, composition changes to become more like colostrum, i.e. increased concentration of immune support factors like lactoferrin. So as you wean, your milk is probably giving your toddler one last super-concentrated shot of immune support.
If you decide to wean completely, I think the conservative course of action would be to wean gradually. 4 nursing sessions per day is a lot to drop at once, but 1-2 is generally quite doable. Nevertheless, take your pump with you on the trip! I'm sure you're tired of it, but you don't want to get overfull and uncomfortable, or engorged, or end up with mastitis, and also be far from home and your own doctor.
